The Dynamics of Visual Reweighting in Healthy and Fall-Prone Older Adults

Multisensory reweighting (MSR) is an adaptive process that prioritizes the visual, vestibular, and somatosensory inputs to provide the most reliable information for postural stability when environmental conditions change. This process is thought to degrade with increasing age and to be particularly deficient in fall-prone versus healthy older adults. In the present study, the authors investigate the dynamics of sensory reweighting, which is not well-understood at any age. Postural sway of young, healthy, and fall-prone older adults was measured in response to large changes in the visual motion stimulus amplitude within a trial. Absolute levels of gain, and the rate of adaptive gain change were examined when visual stimulus amplitude changed from high to low and from low to high. Compared with young adults, gains in both older adult groups were higher when the stimulus amplitude was high. Gains in the fall-prone elderly were higher than both other groups when the stimulus amplitude was low. Both older groups demonstrated slowed sensory reweighting over prolonged time periods when the stimulus amplitude was high. The combination of higher vision gains and slower down weighting in older adults suggest deficits that may contribute to postural instability.     

Sensory Integration and Response to Balance Perturbation in Overweight Physically Active Individuals

The purpose of this study was to compare sensory integration and response to balance perturbation between physically active normal weight and overweight adults. Physically active young adults were grouped into normal weight (n = 45) or overweight (n = 17) according to the World Health Organization body mass index classification for Asian adults. Participants underwent two balance tests: sensory organization and motor control. Overweight participants presented marginally lower somatosensory score compared to normal weight participants. However, they scored significantly higher in response to balance perturbation. There was no difference in the onset of participants' active response to balance perturbation. Physical activity might have contributed to improved muscle strength and improved the ability of overweight individuals to maintain balance.     

Effect of Training on Sensory Room and Cart Usage

In this study, the authors assess the effectiveness of education on the consistency of use of sensory rooms within a large mental health facility. Eleven staff and thirty-six clients received additional multimodal education in sensory strategies, the use of the sensory rooms on their assigned units, and the link between the rooms and clients' personal crisis intervention plans. Staff knowledge and room usage rates were analyzed pre- and post-training. The authors found statistically significant increases in staff knowledge post-training and increases in the use of the sensory rooms by study participants. The results support the effectiveness of training which uses hands-on, population-specific strategies.     

A Guide to Women in Management

The majority of occupational therapists are female clinicians who tend to be motivated by human service. They do not tend to be motivated by administrative or managerial responsibilities beyond those essential to local disciplines functions. More occupational therapists may become interested in management once they are aware of sociocultural assumptions and prejudices as well as the specific qualifications and competencies involved. Sex role stereotyping and some roles are reviewed. Assertiveness training and basic management competencies are listed as pertinent skill acquisitions.     

Sensory Processing Differences in Children Diagnosed With Tourette's Disorder

The objectives of this research were to determine whether sensory processing differences existed in children between the ages of 5 and 10 years diagnosed with Tourette's disorder and to examine whether further differences existed if these children had an additional diagnosis of Attention Deficit Hyperactivity Disorder. The Short Sensory Profile was completed by caregivers for 75 children with Tourette's disorder, 47 who were also diagnosed with Attention Deficit Hyperactivity Disorder. Differences in sensory processing were identified in the total sample. More significant differences were found in the group of children with dual diagnoses, especially in the area of auditory processing.     

Post-Traumatic Stress Disorder,Sensory Integration,and Aquatic Therapy: A Scoping Review

The prevalence of post-traumatic stress disorder (PTSD) continues to increase. Symptomology of PTSD include sensory deficits much like those displayed in children with sensory integration (SI) disorder. The aim of this scoping review is to review symptoms of PTSD and SI, and make a case of how aquatic therapy may be an effective modality in treating clients with PTSD. Eighteen articles were selected for review. From this review, it is suggested that aquatic therapy can be an effective modality in reducing symptoms of PTSD; however, future research is essential in determining its effectiveness.     

Sensory Discrimination,Working Memory and Intelligence in 9‐Year‐Old and 11‐Year‐Old Children

More than a century ago, Galton and Spearman suggested that there was a functional relationship between sensory discrimination ability and intelligence. Studies have since been able to confirm a close relationship between general discrimination ability (GDA) and IQ. The aim of the present study was to assess whether this strong relationship between GDA and IQ could be due to working memory (WM) demands of GDA tasks. A sample of 140 children (seventy 9‐year‐olds and seventy 11‐year‐olds) was studied. Results showed that there was a significant overlap between WM, GDA and fluid intelligence. Furthermore, results also revealed that WM could not explain the relationship between GDA and fluid intelligence as such, but that it acted as a bottleneck of information processing, limiting the influence of GDA on the prediction of fluid intelligence. Specifically, GDA's influence on the prediction of intelligence was only visible when WM capacity was above a certain level. Copyright © 2013 John Wiley & Sons, Ltd.     

Do you remember where sounds,pictures and words came from? The role of the stimulus format in object location memory

Contrasting results in visual and auditory spatial memory stimulate the debate over the role of sensory modality and attention in identity-to-location binding. We investigated the role of sensory modality in the incidental/deliberate encoding of the location of a sequence of items. In 4 separated blocks, 88 participants memorised sequences of environmental sounds, spoken words, pictures and written words, respectively. After memorisation, participants were asked to recognise old from new items in a new sequence of stimuli. They were also asked to indicate from which side of the screen (visual stimuli) or headphone channel (sounds) the old stimuli were presented in encoding. In the first block, participants were not aware of the spatial requirement while, in blocks 2, 3 and 4 they knew that their memory for item location was going to be tested. Results show significantly lower accuracy of object location memory for the auditory stimuli (environmental sounds and spoken words) than for images (pictures and written words). Awareness of spatial requirement did not influence localisation accuracy. We conclude that: (a) object location memory is more effective for visual objects; (b) object location is implicitly associated with item identity during encoding and (c) visual supremacy in spatial memory does not depend on the automaticity of object location binding.     

Parental Choices and the Prospect of Regret: An Alternative Account

Is the question ‘will you regret it if you do (not do) this?’ helpful when people face difficult life decisions, such as terminating a pregnancy if a disability is detected or deciding to become a parent? Despite the commonness of the question in daily life, several philosophers have argued lately against its usefulness. We reconstruct four arguments from recent literature on regret, transformative experience and the use of imagination in deliberation. After analysis of these arguments we conclude that the prospect of regret remains a useful deliberative heuristic, provided four conditions are fulfilled. If the prospect of (the absence of) regret is arrived at via reflection on one’s values, in a non-coercive context, when well-informed about factual circumstances, and in a process of self-commitment, the question of what one will regret is a helpful device to get in touch with one’s deepest concerns that give reasons to act in a particular way.     

Associative dreaming: reverie and active imagination

The idea of countertransference has expanded beyond its original meaning of a neurotic reaction to include all reactions of the therapist: affective, bodily, and imaginal. Additionally, Jung's fundamental insight in 'The psychology of the transference' was that a 'third thing' is created in the analysis, but he failed to demonstrate how this third is experienced and utilized in analysis. This 'analytic third', as Ogden names it, is co-created by analyst and analysand in depth work and becomes the object of analysis. Reverie, as developed by Bion and clinically utilized by Ogden, provides a means of access to the unconscious nature of this third. Reverie will be placed on a continuum of contents of mind, ranging from indirect to direct associative forms described as associative dreaming. Active imagination, as developed by Jung, provides the paradigm for a mode of interaction with these contents within the analytic encounter itself. Whether the analyst speaks from or about these contents depends on the capacity of the patient to dream. Classical amplification can be understood as an instance of speaking about inner contents. As the ego of the analyst, the conscious component, relates to unconscious contents emerging from the analytic third, micro-activations of the transcendent function constellate creating an analytic compass.
